In one molecule of common table salt (NaCl), there are two types of atoms: one sodium (Na) atom and one chlorine (Cl) atom. Each type of atom represents an element, so salt contains two elements: sodium and chlorine.
There are no hydrogen atoms in salt (sodium chloride). Salt is composed of sodium and chlorine ions, not hydrogen atoms.
N2O5 has 2 nitrogen atoms, 5 oxygen atoms, and 2 elements - nitrogen and oxygen.
There are 22 elements in a molecule of C8H11NO2: 8 carbon atoms, 11 hydrogen atoms, 1 nitrogen atom, and 2 oxygen atoms.
No, salt and sugar are not examples of elements. Salt is composed of sodium and chloride ions, while sugar is composed of carbon, hydrogen, and oxygen atoms. Elements are the basic building blocks of matter and cannot be broken down into simpler substances.
A molecule is made up of a specific number of atoms bonded together. The number of atoms that make up a molecule depends on the chemical formula of the molecule and the types of atoms bonded together.
